Hi FreeGirl
An erection is when a boys penis grows to it's full extent and hardens, this normally happens when he sees something sexually pleasurable (something like watching porn, looking at nude woman etc)
When you ever have sex you'll notise right away whether or not the boy is sexually "turned on", I guess this happens more so when going through male puberty, like I did.With regards to how it feels, I guess it's hard to explain in words, but all it is is just feels hard, and is quite stubborn to be positioned anywhere other than straight ahead..
Hope this helps, take care, Aleksandr xx
